Timothée Chalamet’s sartorial playfulness has been a consistent theme as he stepped out in memorable looks for each red carpet event over the last few months. For the Oscars, the most conservative red carpet of them all, he did not disappoint.

Chalamet arrived in a monochromatic butter yellow custom Givenchy suit designed by Sarah Burton. A leather double-breasted cropped jacket with a notch lapel was paired with matching pants and a silk shirt.

“Love that suit,” Conan O’Brien said to Chalamet during the show’s opening monologue. “You will not get hit on your bike tonight.”

Chalamet’s girlfriend, Kylie Jenner, was cozied up next to him in the audience in a brown Miu Miu bustier gown with black crystal embroidery and cutouts. (Jenner did not attend the Screen Actors Guild Awards last weekend, which was held shortly after her friend and hair stylist, Jesus Guerrero, died.)

A best actor nominee for his portrayal of Bob Dylan in the biopic “A Complete Unknown,” Chalamet, 29, nonchalantly bobbed down the red carpet, hands behind his back, in his pastel outfit.

Leading up to the release of his film in December, through the months that followed on the awards trail, Chalamet has waged a viral campaign that diverted from the old, staid ways of Hollywood promotion. That has included a slew of eye-catching outfits, including an all-pink ensemble consisting of a Chrome Hearts hoodie and tank top that he wore at the Berlin International Film Festival.

And at the SAG Awards, where he wore a black leather suit paired with a lime green shirt, he accepted his best actor award with a speech that reaffirmed that he was serious about his job: “I’m really in pursuit of greatness,” he said. “I know people don’t usually talk like that but I want to be one of the greats.”

Whether he takes home best actor tonight or not, he takes the prize for men’s wear with his “movie-star trucker vibe,” as our men’s wear critic Guy Trebay wrote.
